ITO all wiom'it may concern l Be it known that\],2Ei\ia1-iuiii.` FISHER, citizen ,of the United States, residing at county of Providence` and useful Improvements My .,'nvention relates, to rotary valves adapted foimuse `with. steam, gas,air,vflu1ds `:The `essential objects of my.` .invention aref l,to `provide. a compoundopening on one porti .to assure an inside` lead and an increase oi';

pressure when the `valve is turned 180o fromE its closed `positionso as to insure a was i and accumulations will `be initially removed from .behind the valve; to insure the pas* sageof a greater volume of V.water and ai greater opening .area .in a given time and `by ak smaller movement. i

Further objects are certainty of operationf simplicity` and inexpensiveness `of construe.i

`*In its .present and preferred., embodiment iny valve comprises the valve casing A, and threaded pipe openings B and C. An` end plateD, attachedto the casing by: screws d,

is` provided with `an vopening d through which passes the valve spindle E, extending" t also througha :stuing boXarrangement A .handle- H `is fixed `to the end of the valve stem. rThe interiorof thewallofthe casingy is. cylindrical, lout the .intermediate l portions A`of its sides are` recessed leavingdepressions -c arranged longitudinally y. nal .bearing `face, also cylindrical `,bearing exten- `.valve seat .J l and :when Athe valveis closed 4relativelyraised valve `seat J, and intermediate annular portions je against which the rings N bear.

ThevalVe. memberV I comprises `'a longitudiweb having. a substantially cylindrical ,i

In Fig. 5, Tthe. valve M is shown adVaIlCed .tovsuch';aydegreens `to entirely disclose thel i `or clearances j at both sides of a resultant port'K and the coincidence of the surface p. with the left hand portion of the valve seat J cuts'v off from the port in advance the liquid to the latter through the clearance When the valve is turned to a position directly opposi te its full closedposition, which latteriis shown in Fig. 2, the valve being moved 180, the water flowing in both directions through the clearances j upon opposite sides cf the valve will be lunder increased pressure yand will serve to more effectively and efficiently vremove `all mud or sediment not only from" the working faces p of the valve but also from the walls of the clearances and of the valve seat J.

Not only-is a wash upon both sides of the valve obtained by my structure, but the volume of liquid or lfluid is controlled bya minimum of valvewtravel and expenditure of time. The serrated character of the port opening'K is found to be particularly advantageous in the operation of the y structure, but it will be understood that satisfactory lresul-ts are secured with valve openings of my valve andv its' described construction feasible..v

of unserrated form. `The rotary character makes its operation in a direction opposite to that indicated by the arrows equally 'What I claim is 1. In a valvea casing provided with a portand a valve seat surrounding the same 'with a clearanceupon each side of said seat, and a valve member rotatably mounted and `comprising a transversely curved web provided'with'worlring faces adapted to cooperate with said port and seat and to permit of a double opening, whereby the fluid may ow 'through at either sideof the valve member and permitting the fluid to flow across the seat upon opposite sides of said port when the valve is open.v QQInja valve, a casing provided with a port havinga series of connected V-shaped openings vand a l'valve member rotatably mounted andhaving a transversely curved web for' cooperation with. said seat .and to straddle said port when the valve is closed, there vbeing a kclearance upon each side of said seat whereby vfluid is permitted to flow across the seat upony both sidesof vthe port whe'nthe valve is open. i n v `3. In afvalve, a cylindrical casing provided withk recessed portions providing clearances and a valve seat intermediate the same and provided with a port, and a valve rotatably mounted yin the casing and comprising a web provided with bearing faces interi "spaced from each other substantially the @.60

4. Ina valve, a cylindrical casing pro-I vided with recessed portions providing clearances and a valve seat intermediate the same and provided with a port comprising a series of connected V-shaped openings, and a valve rotatably mounted in said casing and comprising a web provided with two parallel curved bearing faces interspaced from each other substantially the width of the port and adapted to slide upon said seat to permit fluid to flow through the inlet opening of the casing simultaneously around both sides of the valve. f

5. In a valve, a cylindrical casing provided with recessed portions providing clearances and a valve seat intermediate the same and provided with a port comprising a plurality of V-shaped openings, a valve comprising a web provided with parallel interspaced working faces adapted to engage the seat and spaced apart substantially the width of the port and constructed to permit the flow of fluid from the opening in the casing substantially around both sides of the valve, eX- tension rings upon the ends of the valve, and a valve stem for said valve.

A valve comprising a chamber, an inlet thereto, a rotatable valve member within the chamber with its axis parallel with the said chamber, an outlet beyond the valve, a valve seat surrounding the outlet and a recess within the valve chamber and extending to the valve seat, whereby fluid is permitted to iow across both seats when the valve-is open.

8. A valve comprising a chamber, a valve member rotatable in the chamber, an inlet port to the chamber and an outlet port leading therefrom, seats facing toward the inlet, faces spaced apart on said valve adapted to cooperate with said'seats, to control the outlet, the chamber being recessed between said seats andsaid inlet port to allow fluid to flow across both seats when the valve is open, the width of each of the said faces being substantially the same as the width lof the individual portions of the valve seat yat either side of its port.
